You can find a lot of catechin, gallic acid, epicatechin, and chlorogenic acid in bitter melon. These are all powerful antioxidants that can help keep your cells from getting hurt.
Taking 2,000 mg of bitter melon every day for three months lowered blood sugar and haemoglobin A1c, a test used to track blood sugar control. This was seen in 24 people with diabetes who took part in the study.
On top of that, the supplement greatly lowered fructosamine levels, which is a short-term sign of long-term blood sugar control.
There is evidence that bitter melon can help your body better use sugar and increase the production of insulin, the hormone that controls blood sugar.
Similar results were found in a study that used both test tubes and animals. Bitter melon extract stopped the growth and spread of breast cancer cells and helped the cells die.
